Abstract

A series of vehicle seats, in particular airline passenger seats, which can be adjusted from three seats of normal width to two seats of enlarged width and vice versa, displays a coupling device through which two side parts of the seat back of the middle seat can be connected alternatively with the middle part or the seat backs of both outside seats. The coupling device connects the gear with the hand lever through a telescopically elongatable shaft only in the swinging area of a hand lever used for an adjustment between the middle position and an end position. The elongatable shaft includes a first section equipped with a spline bore hub and a second section that can be shifted axially relative to the first, which is formed on one part of its length like a spline shaft which only meshes with the spline bore hub when the gears connect.

Dependent claims

A series of passenger seats which have a seat frame common to all seats where at least one seat can be pushed lengthwise in relation to a neighboring seat between two positions in which the series of seats displays a maximum and minimum width and, in these positions, can be locked connected to a seat frame, comprising:

a lever movable in different swinging positions located at one end of seat dividers which separate individual seats, for locking or releasing said seats when the series of seats is adjusted to its minimal or maximum width;
an elongated shaft having a first section with a spline bore hub, and a second section which can shift axially in relation to the first section, said second section including a spline which meshes with said spline bore hub when connected;
a coupling device which connects the lever with said shaft;
and
whereby in the case of a transformation of three seats of normal width into two seats of enlarged width and vice versa, two side parts of seat backs of a middle seat can be connected alternatively with a middle part or with the seat backs of both outside seats.
